"Be it known that we, ROBERT S. WHITE,

J12, and CHARLES N. BANGROFT, citizens of the United States, residing at Bickford, in

the county of 'Blaine, State of Oklahoma, have invented a new, and useful Rotary 'Wall-Block Machine, of' which the follow- -is a specification.

t is the object of this invention to provide novel means whereby a air of spaced conveyers may be-employed or-the double purpose of conveying away a series of molds, and for forming the tops and bottoms of the molds.

' Another'object of the invention is to provide novel means for pro erly positioning the molds with respect to t e conveyers.

A further object of the invention is to provide novel means for conveying away the finished product of the molds, and to provide novel means for returnin the constituent elements of the molds, a er the products thereof have been fashioned.

Another object of the invention is toprovide a mold of novel and improved form.

ulleys 7, about which isfio end of the machine, as clearly appearing in Fig. 1. The shafts 11 carry pulleys 12, about which is assed a belt 14, the lower run of which is old depressed by means of "to rollers 15, journaled for rotation, transversely of the frame 1, in frame-supported bearing brackets 16.

Disposed transversely of the frame 1, and supported thereby, intermediate the forward end of the frame 1 and one of the pulleys 12 about which the belt 14 is passed, is a scraper, comprising a bar 46, carrying depending, resilient blades 47.

The invention further includes an'auxil-eao iary frame 17, extended in the same :direction as the framel, and located adjacent the rear end of the frame 1. In the auxiliary frame 17, there is journaled for rotation a shaft 18, carrying a pulley 19, about which has is trained a belt 20. The upper run of the belt ,20 is disposed in the same plane as the upper run of the belt 8. Likewise journaled for rotation in the auxiliary frame 17 and located above the shaft 18, is another 30 shaft 21, carrying'a pulley 22, about which is trained a belt 23. The upper run of the belt 23 is disposed substantially in a common plane with tlieupper fun of the belt 14, a suitable bridge plate 24 being dis- '85 posed between the adjacent ends of thebelts 14 and 23.

Along the inner faces of the hand, are oppositely disposed guides -25, extended longitudinally of the frame. Disposed ao'o transversely of the frame 1, adjacent the forward end of the frame, but spaced therefrom, and fulcrumed at 26 upon the frame, is a lever 27, one end of which 'is extended beyond'the frame, as shown at 28, the extension 28 of the lever terminating in a foot plate 29. The free end of the lever 27 is normally maintained uplifted, by

- meansof =-a retraetile spring 30, one end of which is secured to the 1everz27,iadjaeent F319 jaws 34 are disposed upon either-side of the' will its free end, the other end of the spring 30 being secured to any convenient portion of the frame 1. An auxiliary lever 31 is disposed transversely of the frame 1, this lever 31 being fulcrumed upon the frame, as shown at 32. The fulcrum points 26 and 32 of the levers 27 and 31, respectively, are located upon opposite sides of the frame, the auxiliary lever 31 extending toward the longitudinal center of the frame. The inner end of the auxiliary lever 31 is pivotally connected, as shown at 33, with the intermediate portion of the lever 27. Upright belt '8, these jaws 34 being pivotally connected, as shown at 34, with the levers 27 and 31. The jaws 34 are adapted to recip rocate vertically, at right angles to the guides 25.

The structure hereinbefore described, is adapted to be.employed in connection with a series of molds, and before explaining the manner in which these molds are employed in connection with the machine, a description of the molds themselves, will be given.

Noting Figs. 6 to 11 particularly, it will be seen that each mold consists of a pair of end plates 35, oppositely disposed. Each of the end plates 35 is notched, adjacent one end, as shown at 36, to receive a division plate 37, these division plates 37 forming the sides of the molds. Each division plate 37 is supplied with an outstanding, longitudinally disposed rib 38. The end plates 35 are provided with transverse flanges 39, adaptedto register in grooves 40 of the next adjoining side plates, the construction being such that a long series of side plates 35 may be terminally interlocked, the partitions 37 being held in place in the grooves. 36, as hereinbefore described.

Extended transversely of the mold, is a core 41. There may be any number-of these cores, depending upon the number of openings which it is desired to form in the finished block. Each core 41 embraces a tubular, resilient covering 42,'to the inner face of which are secured a series of segmental, longitudinally extended blocks 43. Proecting inwardly from the side plates 35, are angularly disposed tongues 44, the ex-. tremltles of wh' :h are beveled, as shown at 45. These tongues 44 are adapted to register 1n the spaces between the segmental blocks 43 of the core, in order to expand the covering 42, as will be described hereinafter.

In order that blocks of difi'erent thicknesses may be fashioned in the same machine, the pulleys 11, the belt 14 and the rollers 15 are made vertically movable. To efiect this end, that portion of the frame 1 which carries the elements above enumerated, is adjustably united with the base portion of the frame, as denoted by the numeral 100inFigz-4.

menace "The operation of the device is as follows:

The side plates 35 are set up longitudinally of the machine, adjacent the forwardend thereof, the tongues 44 of the side plates 35 entering the openings between the se ental blocks 43 of the cores 41, and expan ing the covers 42. The partitions 37 are mounted in place in the grooves 36, the ribs 38 of the partitions extending toward the center of the mold. The side plates 35 of one mold are assembled with the side plates 35 of the next adjacent mold, by inserting the flanges 39 of the side plates 35 of one mold, into the grooves 40 of the mold next adjacent. The concrete or other plastic material is shoveled upon the upper run of the belt 8, adjacent the forward-end of the machine between the side plates 35, and beneath the cores 41, as denoted by the numeral 48 in Fig. 3. The concrete which is beneath the cores 41 serves to support the side plates 35 prior to the engagement of the side plates with the jaws 34. Referring to Fig. 3 it will be noted that the side plates 35 upstand at a considerable distance above the upper/ run of the belt 8, thus permitting the concrete to be deposited below the cores 41. The operator, taking his stand upon a suitable platform 49, located adjacent the forward end of the machine, seizes the lever 5 and rotates the drive shaft 2, advancing the upper run of the belt 8.

Theseveral molds which rest upon the upper run of the belt 8 Will thus be carried forward. The side plates 35 of the molds will ultimately pass within the jaws 34. The foot of the operator is then placed upon the plate 29 of the lever 27, whereupon, throu h the cotiperation of the levers 27 and 31, t e

jaws 34 will. be depressed, carrying with them the side plates 35 of the mold. The molds will thus be depressed, so that the side plates 35 occupy approximately the positions shown in Fig. 4. The concrete will thus be permitted to pass beneath the scraper bar 46, the elements 47 of which will scrape the surplus concrete forwardly, into the next adjoining mold. The belt 8 will thus advance the molds and dispose their contents between the lower run of the belt 14, and i the upper run of the belt 8, the upper run of the belt 8 and the lower run of the belt 14 advancing inthe direction of the arrow S in Fig. 3, the belt 14 being actuated in any desired manner. It will be seen that the belts 14 and 8-thus cotiperate to form the upper and lower surfaces of the finished block. The continued movement of the belt 8 ultimately deposits the molds and the blocks upon the upper run of the auxiliary conveyer belt 20. The molds may now be removed from the finished block, the mold parts being placed upon the up er run of the belt 23, which will deliver t eseparts, through the instrumentality of the bridge within reach of the operator, whereupon the parts may be assembled again,- for further I cooperation with the belts 14 and 8. While the molds are movingwith the belts Hand 8, a leakage between the upper run of the belt 8 and .the plates 35 isprevented bgere silient strips 50, supported upon the aring brackets 10, as s own in Fig. 4, these elements50 fitting closely within the angles defined by the lower run of the belt 8 and the plates 35 of the molds.

When the molds are disposed above the forward end of the lower belt 8, as shown at the left hand end of Fig. 3, the concrete may be shoveled readily beneath the cores 41, Subsequently, the molds may be depressed, in the manner hereinbefore de-' scribed, the concrete which lies between the cores 41 and. the upper run of the lower belt '8 being compacted and pressed upwardly above the cores. When the concrete then passes beneath the scraper blades 47, these blades, being resilient, will compact the concrete which lies above the cores 41, thus making the product homogeneous. When the molds move with the belts 8 and 14, the upper surfaces of the blocks will be rendered smooth, by reason of the fact that the lower run of the belt 14 is held against.

the upper-face'of the material by means of therollers 15. It will be recalled that a con:

nected string of molds is continuously passing along withthe belts 8 and 14. To advance the strin of connected molds, throu h friction with t e lower belt only, would e mechanically impossible, in the absence of owing to the fact that the u per belt 14 engages the molds. The mol 5, therefore,

are engaged along their upper and lower edges, between the spaced belts, the construction 'being such that the entire string of lower run of the belt 14, the opposite face I being fashioned by the upper run of the belt-8. The side faces 56 pf the block are fashioned by the side plates 35, the end faces 57 of the block 53 being fashioned by the partitions 37. The ribs 38 of the plates 37 serve to fashion the tongues and grooves 58 and 59 respectively, in the block, the cores 41 forming the openings 60 in the finished block.

Having thus described the invention, what is claimed is 1. A mold comprising a core consisting of a yieldable covering and segmental blocks within the covering; and side members having outstanding elements adapted to enter between the blocks to expand the covering.

2. In a device of the class described, core supporting side plates; a conveyer; means for moving the side plates. with respect to the conveyerg' and means for advancing the conveyer transversely of the direction of movement of the side plates.

3. In a device of the class described, a frame; interlocked :levers supported by the frame; a ,conveyer; jaws carried by the levers and movable'with respect to the conveyer; mechanism for advancing the conveyer transversely of the direction of movement of the jaws; and core supporting side plates engageable by the jaws.

In testimony that we claim the foregoing as our own, we have hereto aflixed our signatures in the presence ofntwo witnesses. c
